Abstract
The aluminum alloy for anodic oxidation treatment directed to the present invention comprises as alloy elements 0.1 to 2.0% Mg, 0.1 to 2.0% Si, and 0.1 to 2.0% Mn, wherein each content of Fe, Cr, and Cu is limited to 0.03 mass % or less, and wherein the remainder is composed of Al and inevitable impurities. An aluminum alloy more excellent in the durability can be obtained by subjecting the aluminum alloy ingot having the above element composition to a homogenization treatment at a temperature of more than 550° C. to 600° C. or less. An aluminum alloy member can be obtained by forming an anodic oxidation coating on the surface of the aluminum alloy.
